The main structural components are made on the assembly line of the house factory and transported to the construction site. The main structure is assembled on site by the installation workers, and all the structural components are mass-produced in the house factory, and only assembly work is required on site. All components are made in the factory, and on-site assembly realizes the prefabrication of components in the factory and on-site assembly construction. There is no wet operation, less noise, dust and garbage, and less impact from the climate; clay bricks are not used, and they can be disassembled and recycled. It only takes 5 days to install the system structure of a 200-square-meter independent house. The subsequent interior decoration projects such as doors and windows, sanitary ware, kitchen supplies, etc. are all standardized and serialized designs, factory-produced, and each product provides a menu-style selection. This not only saves construction time, but also solves the late hidden dangers caused by manual decoration.
